So are you saying that you have a DNN site installed on a production server and all the content entered for it with only the adminstrator having access? If that is the case you just need to go to the page settings of each page and set the permissions for what additional groups you want to have edit rights and what users you want to have read right. 

If the site has a lot of pages, it might not be reasonable to edit each page and manually set the settings.  If that is the case you can write a SQL script to update each of the page permissions.  Depending on how you want to have your permissions setup on each page, and whether the permission are the same for all pages will determins how complex this SQL script is.  Someone might already have a script written to do this that you can just modify for you purpose.  If you do want to automate the process to set the permissions on the page, just state that in your reply. That way we can help you as much as possible to get this done, or at least provide you with the information you need to do what you want.

Shawn - I did what you suggested and set the read rights in the page settings, but users still cannot access the site. Any suggestions?
